Answer 2

Given,

A set of equations to be solved.

To Find,

The smallest value among the given equations.  

Solution,

Equation 1, when solved : $-777 + 7 = -770$

Equation 2, when solved : ${7+(7)(7)} +7-7 = {7+49}+7-7 = 56 + 7 - 7 = 63-7 = 56$

Equation 3, when solved : $7-(7)(77) +7 = 7-539+7= 7- 532 = -525$

Equation 4, when solved : $7-{7+(7)(7)+7} = 7-{7+49+7} = 7-63 = - 56$

For solving the above equations, the rule of BODMAS is used.

Where BO = Bracket Off, D = Division, M = Multiplication, A = Addition and S = Subtraction.

From the above-solved equations, it can be seen that the smallest number is $-770$.

Henceforth, equation 1 gives the smallest value.
